The expansion of spacetime produces detectable cosmological signatures
Multiple recent theoretical models and observational frameworks indicate that the expansion and dynamic properties of spacetime yield detectable cosmological signatures, ranging from scale-dependent expansion features to structured redshift dispersions.
The retrieved papers present various theoretical frameworks (fractal spacetime, torsion, expansion-flow models, and emergent arithmetic structures) demonstrating that the expansion and nature of spacetime generate specific, testable cosmological signatures. None of the papers refute the general premise that cosmological expansion can produce signatures; instead, they propose different mechanisms for detecting them. Thus, the claim is well supported.

Paper [2] proposes that cosmic expansion dynamics and fractal microstructure leave observable signatures in the Hubble expansion history and SNIa samples.
